(<b><a href="intro.html#tag_001_003_003">LEGACY</a></b>)</blockquote><h4><a name = "tag_001_014_2050"> </a>SYNOPSIS</h4><blockquote><pre><code>spell <b>[</b>-bvx<b>][</b>+<i>local_file</i><b>][</b><i>file</i>...<b>]</b></code></pre></blockquote><h4><a name = "tag_001_014_2051"> </a>DESCRIPTION</h4><blockquote>The<i>spell</i>utilitycollects words from the namedfilesand looks them up in a spelling list.A<i>word</i>in this context is a series of characters from the set:<pre><code>[A-Za-z0-9'&.,;?:]</code></pre>in the POSIX locale, where the first and last characters are alphanumeric.Words that neither occur among nor are derivable(by applying certain inflections,prefixes and suffixes) from words in the spelling listare written to standard output.<p>Within the file, certain character sequences are treated specially;if the file contains lines that begin with a periodor apostrophe or that contain backslashes in any position,the results are unspecified.</blockquote><h4><a name = "tag_001_014_2052"> </a>OPTIONS</h4><blockquote>The<i>spell</i>utility supports the <b>XBD</b> specification, <a href="../xbd/utilconv.html#usg"><b>Utility Syntax Guidelines</b> </a> ,except that the<i>+local_file</i>option takes a leading plus sign instead of minus.The following options are supported:<p><dl compact><dt><b>-v</b><dd>Write all words not literally in the spelling list.Plausible derivations from the words in the spelling listmay be indicated.<dt><b>-b</b><dd>Check British spelling.Besides preferring<i>centre</i>,<i>colour</i>,<i>programme</i>,<i>speciality</i>,<i>travelled</i>,and so on, this option insists upon<i>-ise</i>in words like<i>standardise</i>.<dt><b>-x</b><dd>Write every plausible stem with"="for each word.<dt><i>+local_file</i><dd>Remove words found in<i>local_file</i>from the<i>spell</i>command output.The argument<i>local_file</i>is the name of a user-provided file that contains a sorted list of words,one per line.With this option, the user can specify a set of wordsthat are correct spellings (in addition to<i>spell</i>'sown spelling list) for each job.</dl><br></blockquote><h4><a name = "tag_001_014_2053"> </a>OPERANDS</h4><blockquote>The following operands are supported:<dl compact><dt><i>file</i><dd>A pathname of a text file to check for spelling errors.If no files are named, words are collected from the standard input.</dl></blockquote><h4><a name = "tag_001_014_2054"> </a>STDIN</h4><blockquote>The standard input is a text file used only if no<i>file</i>operands are specified.</blockquote><h4><a name = "tag_001_014_2055"> </a>INPUT FILES</h4><blockquote>The input files are text files.</blockquote><h4><a name = "tag_001_014_2056"> </a>ENVIRONMENT VARIABLES</h4><blockquote>The following environment variables may affect the execution of<i>spell</i>:<dl compact><dt><i>LANG</i><dd>Provide a default value for the internationalisation variablesthat are unset or null.If<i>LANG</i>is unset or null, the corresponding value from theimplementation-dependent default locale will be used.If any of the internationalisation variables contains an invalid setting, theutility will behave as if none of the variables had been defined.<dt><i>LC_ALL</i><dd>If set to a non-empty string value,override the values of all the other internationalisation variables.<dt><i>LC_CTYPE</i><dd>Determine thelocale for the interpretation of sequences of bytes of text data ascharacters (for example, single- as opposed to multi-byte charactersin arguments and input files).<dt><i>LC_MESSAGES</i><dd>Determine the locale that should be used to affectthe format and contents of diagnosticmessages written to standard error.<dt><i>NLSPATH</i><dd>Determine the location of message cataloguesfor the processing of<i>LC_MESSAGES .</i></dl></blockquote><h4><a name = "tag_001_014_2057"> </a>ASYNCHRONOUS EVENTS</h4><blockquote>Default.</blockquote><h4><a name = "tag_001_014_2058"> </a>STDOUT</h4><blockquote>The standard output consists of single misspelled words separated by newlines.If the<b>-x</b>option is used, words can be preceded by"=".</blockquote><h4><a name = "tag_001_014_2059"> </a>STDERR</h4><blockquote>Used only for diagnostic messages.</blockquote><h4><a name = "tag_001_014_2060"> </a>OUTPUT FILES</h4><blockquote>None.</blockquote><h4><a name = "tag_001_014_2061"> </a>EXTENDED DESCRIPTION</h4><blockquote>None.</blockquote><h4><a name = "tag_001_014_2062"> </a>EXIT STATUS</h4><blockquote>The following exit values are returned:<dl compact><dt>0<dd>Successful completion.<dt>>0<dd>An error occurred.</dl></blockquote><h4><a name = "tag_001_014_2063"> </a>CONSEQUENCES OF ERRORS</h4><blockquote>Default.</blockquote><h4><a name = "tag_001_014_2064"> </a>APPLICATION USAGE</h4><blockquote>None of the internationalisation variablesare required to affect the processing of the input source language.In the POSIX locale, the<i>spell</i>utility recognises English (American or Britishdialects, depending on the<b>-b</b>option) text.<p>The unspecified nature of<i>spell</i>when presented files with backslashes or leading periods or leadingapostrophes results from its complex attempts to deal with filesformatted for<i>troff</i>,<i>tbl</i>and<i>eqn</i>processing (none of which are specified by this specification).Constructs such as.so,.nx,.TS,.EQ,.ig,\sand\fare frequently dealt with in a manner that ismost useful for determining spelling errors.However, such algorithms are historically lessthan perfect and are very difficult to describe precisely.<p>This utility is marked LEGACY because there is no knowntechnology that can be used to make it recognisegeneral language for user-specified input withoutproviding a complete dictionary along with the input file.</blockquote><h4><a name = "tag_001_014_2065"> </a>EXAMPLES</h4><blockquote>None.</blockquote><h4><a name = "tag_001_014_2066"> </a>FUTURE DIRECTIONS</h4><blockquote>None.</blockquote><h4><a name = "tag_001_014_2067"> </a>SEE ALSO</h4><blockquote>None.<br></blockquote><hr size=2 noshade><center><font size=2>UNIX ® is a registered Trademark of The Open Group.<br>Copyright © 1997 The Open Group<br> [ <a
